氢氧化钾是一种常见的无机碱，化学式为Koh，分子量为56.1，室温为白色粉末或片状固体。类似氢氧化钠，强碱性，腐蚀性，0.1mol/L溶液，pH13.5。

Potassium hydroxide is a common inorganic base with chemical formula of Koh, molecular weight of 56.1, and white powder or flake solid at room temperature. Similar to sodium hydroxide, strongly alkaline, corrosive, 0.1mol/L solution, pH13.5.

它容易吸收空气中的水分和潮解，吸收二氧化碳形成碳酸钾。溶于热水0.6份，冷水0.9份，乙醇3份，甘油2.5份，略溶于乙醚。当溶解在水、酒精或酸处理时，会产生大量热量。中度毒性，中致死剂量（大鼠，口服）1230mg/kg。

It easily absorbs moisture and deliquescence from the air, absorbing carbon dioxide to form potassium carbonate. Dissolve in 0.6 parts hot water, 0.9 parts cold water, 3 parts ethanol, 2.5 parts glycerol, slightly soluble in ether. When dissolved in water, alcohol, or acid treatment, a large amount of heat is generated. Moderate toxicity, moderate lethal dose (rat, oral) 1230mg/kg.

氢氧化钾是固体氢氧化钠，其化学性能较好。它广泛应用于农业、工业等领域。今天，小编想介绍它在纺织工业中的应用。让我们看看。

Potassium hydroxide is a solid sodium hydroxide with good chemical properties. It is widely used in fields such as agriculture and industry. Today, Xiaobian would like to introduce its application in Textile manufacturing. Let's take a look.

1.颜色好

1. Good color

用本品代替纯碱灰固定，即用产品的1/10代替纯碱灰也能保持较足的供色，少量过量也不会影响纤维在操作过程中的着色。

Using this product instead of soda ash for fixation, even if 1/10 of the product is used instead of soda ash, it can maintain sufficient color supply, and a small amount of excess will not affect the coloring of the fibers during operation.

2.对染料和设备适应性广

2. Wide adaptability to dyes and equipment

适用于各种活性染料，对不同结构的各种活性染料具有较高的显色性和重现性。此外，Koh在各种设备上表现出较好的优势，主要是在低浴比和气雾染色机上。

It is suitable for all kinds of Reactive dye, and has high color rendering and reproducibility for all kinds of Reactive dye with different structures. In addition, Koh has shown good advantages in various equipment, mainly in low bath ratios and aerosol dyeing machines.

3.缩短染色时间

3. Shorten dyeing time

又称缓冲固体碱，溶解时电解质少，离子强度低。因此，在加碱过程中，染色速度慢，使染料的匀染性更好。在深色和浅色中，碱可以在20分钟左右加入，以缩短染色时间。

Also known as buffer solid base, it has less electrolyte and low Ionic strength when dissolved. Therefore, during the alkali addition process, the dyeing speed is slow, resulting in better levelness of the dye. In dark and light colors, alkali can be added in about 20 minutes to shorten the dyeing time.

具有良好的耐蚀性，其次是镍。银和镍能承受氢氧化钠的浓度和温度，直到熔化状态（480℃).适用于高温高浓度碱、镍及其合金（如Cr-Ni-Fe合金、Monel合金等），是较好的选择。

It has good corrosion resistance, followed by nickel. Silver and nickel can withstand the concentration and temperature of sodium hydroxide until melting (480 ℃). It is suitable for high temperature and high concentration alkali, nickel and their alloys (such as Cr Ni Fe alloy, Monel alloy, etc.), and is a good choice.

不锈钢可承受80-100℃NaOH溶液在40%-50%以下，但不能耐受高浓度的高温碱。碳钢在低温稀NaOH溶液中具有良好的耐蚀性，在表面能形成固体氧化保护膜。由于低廉，氢氧化钾往往是很多用户的选择。更多相关事项就来我们网站http://qxu1539600089.my3w.com咨询吧！

Stainless steel can withstand NaOH solutions at temperatures below 40% -50% at 80-100 ℃, but cannot withstand high concentrations of high-temperature alkali. Carbon steel has good corrosion resistance in low temperature dilute NaOH solution and can form a solid oxidation protective film on the surface. Due to its low price, potassium hydroxide is often the choice of many users. For more related matters, come to our website http://qxu1539600089.my3w.com Consult!
